Ivan Kozlovic 4bf81420e2 [FIXED] Fast routed JetStream API requests were dropped ...

If a JS API request is received from a non client connection, it
was processed in its own go routine. To reduce the number of
such go routine, we were limiting the number of outstanding routines
to 4096. However, in some situations, it was possible to issue
many requests at the same time that would then cause those requests
to be dropped.

(an example was an MQTT benchmark tool that would create 5000
sessions, each with one QoS1 R1 consumer (with the use of consumer_replicas=1).
On abrupt exit of the tool, the consumers and their sessions needed
to be deleted. Since would cause fast incoming delete consumer requests
which would cause the original code to drop some of them)
